List of dual Rugby Union World Cup winners

Since the inception of the Rugby World Cup in 1987, a total of twenty rugby players have been dual Rugby World Cup winners. The exclusive club initially included five Australian players, John Eales, Phil Kearns, Dan Crowley, Jason Little and Tim Horan, who were part of both the 1991 Rugby World Cup and 1999 Rugby World Cup Wallabies squads. They were joined in 2007 by South African player Os Du Randt, who played for the Springboks in their 1995 Rugby World Cup and 2007 Rugby World Cup victories. They were joined by 14 All Blacks in 2015, who played in New Zealand's 2011 Rugby World Cup and 2015 Rugby World Cup victories. Of these twenty, New Zealand's Sonny Bill Williams, Jerome Kaino and Sam Whitelock have played in a record fourteen consecutive World Cup wins, while Richie McCaw is the first player to captain his nation to two titles.

As coaching staff, both Steve Hansen and Wayne Smith were members of New Zealand's 2011 and 2015 victories.
